Acquisition of Cogent Fiber Business – Cash Flow

The Cogent Fiber Business’s cash flow was negative at the time of negotiations and during its recent history.

Due to the dire financial condition of the Cogent Fiber Business, it was understood that a payment from T-Mobile to any potential buyer would be required to execute a transaction to give a buyer sufficient cash inflow to offset losses that would be expected until a buyer could optimize the business.

Based on management’s internal modeling at the culmination of the due diligence process, management determined this cash payment to be $700.0 million.

Management is reducing the negative cash flow of the Sprint Business through the payments from the IP Transit Services Agreement, reducing operating costs and increasing revenue primarily by providing optical wavelength and optical transport services over our fiber network, including the owned network we acquired with the Sprint Business.

We are selling these services to our existing customers, customers we acquired with the Sprint Business and to new customers who require dedicated optical transport connectivity without the capital and ongoing expenses associated with owning and operating network infrastructure.

As part of the Transaction, we began incurring costs associated with the TSA.

The amount of these costs will be dependent upon our ability to integrate the operations of the Sprint Business into our operations.

Our cash flow requirements related to the acquisition of the Sprint Business will be dependent upon our ability to reduce the acquired operating costs, our success in retaining the acquired customers and our ability to sell optical wavelength and optical transport services over our fiber network.

Liquidity and cash obligations

In assessing our liquidity, management reviews and analyzes our current cash balances, payments under the IP Transit Services Agreement, accounts receivable, accounts payable, accrued liabilities, capital expenditure commitments, and required finance lease and debt payments and other obligations.

Because of the operating leverage of our network, our annual capital expenditures measured as a percentage of revenues has fallen over the last decade but increased in 2024 to 18.8% from 13.8% for 2023, primarily due to capital expenditures related to our acquisition of the Sprint Business, costs associated with providing wave services, conversion costs related to acquired data centers and adding buildings to our network.

To date, we have been able to raise capital by issuing notes and arranging financing and leases that have had more flexible terms at reasonable cost.

Through our issuance of the IPv4 Notes, we have also been able to access new markets for raising capital.

The combination of this improved operating performance and access to capital has preserved our financial flexibility and buttressed our ability to make distributions to stockholders in the form of cash dividends or through share repurchases.

We have returned $1.6 billion to our stockholders through share repurchases and dividends.

We will continue to assess our capital and liquidity needs and, where appropriate, return capital to stockholders.

Over the next several years, we have significant contractual and anticipated cash outlays, including our indicative dividend payments on our common stock, our maturing debt obligations, interest payments on our debt obligations and Swap Agreement and our projected capital expenditure requirements in order to help execute our business plan, including the integration of Sprint Business.

Based upon the historical growth rate of our dividend, we expect that we would have to provide approximately $399 million in order to meet our expected quarterly dividend payments over the next two years.

requirements as well as our capital spending.

After consideration of these circumstances, we currently plan to continue our current dividend policy.

In light of the economic uncertainties associated with the global economy, including due to the impact from tariffs and trade restrictions, the cash flow requirements of the Cogent Fiber Business, the lingering impact of the COVID-19 pandemic and bank failures and liquidity concerns at certain other banks, our executive officers and Board of Directors have continued to carefully monitor our liquidity and cash requirements.

Based on current circumstances, we decreased our quarterly dividend to $0.02 per share of common stock for the dividend that was paid in the fourth quarter of 2025.

Any future determination regarding dividends, including a decision to increase our quarterly dividend, will be at the discretion of the Board and will depend on the Company’s financial condition, results of operations, capital requirements, any legal or contractual restrictions on the payment of dividends, and other factors the Board deems relevant.

Given uncertainties regarding the potential impact of tariffs and trade restrictions, the global economy, lingering business impact of the pandemic, and the cash flow requirements of the Cogent Fiber Business, we will continue to monitor our capital spending.

Continued Impact of Changing Office Occupancy Rates

Since the onset of the COVID-19 pandemic in 2020, we have experienced certain corporate customers taking a more cautious approach to new configurations and upgrades as well as a reduction in demand for connecting smaller satellite offices as a result of the challenges and uncertainties of the remote work environment that resulted initially from the pandemic.

We also witnessed a deteriorating real estate market in and around the buildings we service with rising vacancy levels and falling lease initiations or renewals, which resulted in fewer sales opportunities for our salesforce and a reduction in VPN opportunities.

As a result, we experienced a slowdown in new sales to our corporate customers, which negatively impacted our corporate revenue growth.

During the year ended December 31, 2024, we continued to see declining vacancy rates compared to their peak during the pandemic and rising office occupancy rates in certain markets in which we operate continuing a trend that began following the end of the pandemic.

Other markets, particularly those in California, Washington D.C.

and the Pacific Northwest, continue to see markedly higher vacancy rates.

These higher vacancy rates may represent a long-term change in office attendance and occupancy rates in these markets.

Despite this overall environment, we are seeing some positive trends in our corporate business.

This was partially due to the increase in office occupancy rates and leasing activity in some markets but also due to new demands for services from corporate customers.

As the option to fully or partially work from home becomes permanently established at many companies, our corporate customers are integrating certain new applications that became part of the remote work environment, which benefits our corporate business as these customers upgrade their Internet access infrastructure to higher capacity connections, and mitigates the overall impact of remote work policies on our corporate business.

Further, if and when companies eventually return to the buildings in which we operate, whether as existing or new tenants, we believe it will present an opportunity for increased sales.

While we believe that demand for office space in the buildings in which we operate will remain among the strongest in the markets in which they are located, and that most employers will eventually require their employees to return to their offices on at least a hybrid basis, the timing and scope of a return to office, particularly in a number of key markets we serve, remains uncertain.

Our total cash, cash equivalents and restricted cash at December 31, 2025 were $205.1 million and our net accounts receivable were $88.1 million.

We believe this level of liquidity reduces our exposure to refinancing risk, potential underperformance of the business or other unforeseen challenges and enhances our ability to pursue acquisitions or operating opportunities.

We intend to hold levels of cash and cash equivalents sufficient to maintain our ability to fund operations and make dividend payments to our stockholders.

Our total indebtedness at December 31, 2024, at par value, was $2.0 billion.

Issuance of $300.0 Million Principal Amount of 2027 Mirror Notes

On June 11, 2024, the Issuers completed the offering of our 2027 Mirror Notes for issuance in a private placement not registered under the Securities Act.

The 2027 Mirror Notes were offered and sold only to persons reasonably believed to be qualified institutional buyers in an unregistered offering pursuant to Rule 144A under the Securities Act and to certain non - U.S.

persons in transactions outside the United States in compliance with Regulation S under the Securities Act.

The 2027 Mirror Notes have the same maturity date and call protection, bear interest at the same rate and otherwise have substantially the same terms as our 2027 Notes;

however, the 2027 Mirror Notes are not fungible (from a trading or tax perspective) with the 2027 Notes and are a separate series of notes from the 2027 Notes.

The 2027 Mirror Notes were issued at a price equal to 98.50% of their face value.

The net proceeds from the offering were approximately $291.9 million after deducting the discount and offering expenses.

We used $114.6 million of the net proceeds from the offering to exercise a contractual option to prepay in full in June 2024 an existing IRU agreement consisting of 31 remaining monthly recurring payments of $4.2 million, at a 12.0% discount rate.

We expect to use the remainder of the net proceeds for general corporate purposes and/or to make special or recurring dividends to Holdings.

The 2027 Mirror Notes were issued pursuant to, and are governed by, an indenture, dated June 11, 2024 (the “2027 Mirror Notes Indenture”), among the Issuers, Holdings, the other guarantors named therein and Wilmington Trust, National Association, as trustee (the “2027 Notes Trustee”).

The 2027 Mirror Notes are jointly and severally guaranteed (the “Guarantees”) on a senior unsecured basis by each of Group’s existing and future material domestic subsidiaries (other than the Co-Issuer), subject to certain exceptions (collectively, the “Subsidiary Guarantors”), and by Holdings (together with the Subsidiary Guarantors, the “Guarantors”).

However, the Holdings is not subject to the covenants under the 2027 Mirror Notes Indenture.

Under certain circumstances, the Guarantors may be released from these Guarantees without the consent of the holders of the 2027 Mirror Notes.

The 2027 Mirror Notes and the Guarantees are the Issuers’ and the Guarantors’ senior unsecured obligations.

The 2027 Mirror Notes and the Guarantees are effectively subordinated to all of the Issuers’ and the Guarantors’ existing and future secured indebtedness to the extent of the value of the collateral securing such indebtedness, and are structurally subordinated to all indebtedness and other liabilities of subsidiaries that are not Subsidiary Guarantors.

Without giving effect to collateral arrangements, the 2027 Mirror Notes and the Guarantees rank pari passu in right of payment with all of the Issuers’ and the Guarantors’ existing and future senior indebtedness, including the 2026 Notes and the 2027 Notes.

The 2027 Mirror Notes and the Guarantees rank contractually senior in right of payment to all of the Issuers’ and the Guarantors’ subordinated indebtedness and are structurally subordinated to any existing and future indebtedness and other liabilities of the Issuers’ non-guarantor subsidiaries.

The 2027 Mirror Notes bear interest at a rate of 7.00% per annum.

Interest began to accrue on the 2027 Mirror Notes on June 11, 2024 is paid semi-annually in arrears on June 15 and December 15 of each year, which commenced on December 15, 2024.

Unless earlier redeemed or repurchased, the 2027 Mirror Notes will mature on June 15, 2027.

After June 15, 2024, the Issuers may redeem the 2027 Mirror Notes, in whole or in part, at a redemption price ranging from 103.5% of the aggregate principal amount of the 2027 Mirror Notes redeemed to par (depending on the year), in each case, as set forth in the 2027 Mirror Notes Indenture, plus accrued and unpaid interest, if any, to, but not including, the date of redemption.

If Group undergoes specific kinds of change in control accompanied by certain ratings events, the Issuers will be required to offer to repurchase the 2027 Mirror Notes from holders at a price equal to 101% of the aggregate principal amount thereof, plus accrued and unpaid interest, if any, to, but not including, the date of repurchase.

Additionally, if Group or any of its restricted subsidiaries sells assets and does not apply the proceeds from such sale in a certain manner or certain other events have not occurred, under certain circumstances, we will be required to use the net proceeds to make an offer to purchase the 2027 Mirror Notes at an offer price in cash equal to 100% of the principal amount of the 2027 Mirror Notes, plus accrued and unpaid interest, if any, to, but not including, the

Page 43 of 96

repurchase date.

In connection with any offer to purchase all or any of the 2027 Mirror Notes (including a change of control offer, asset sale offer or any tender offer), if holders of no less than 90% of the aggregate principal amount of the outstanding 2027 Mirror Notes validly tender their 2027 Mirror Notes, the Issuers, or a third party, are entitled to redeem any remaining 2027 Mirror Notes at the price paid to each holder.

The 2027 Mirror Notes Indenture includes covenants that restrict Group and its restricted subsidiaries’ (including the Co-Issuer’s) ability to, among other things:

incur indebtedness;

issue certain preferred stock or similar equity securities;

pay dividends or make other distributions in respect of, or repurchase or redeem, capital stock;

make certain investments and other restricted payments, such as prepayment, redemption or repurchase of certain indebtedness;

create liens;

consolidate, merge, sell or otherwise dispose of all or substantially all of the properties and assets of Group and its restricted subsidiaries taken as a whole;

incur restrictions on the ability of a subsidiary to pay dividends or make other payments;

or enter into transactions with affiliates.

The covenants provide for certain exceptions to these restrictions, and Holdings is not subject to the covenants under the 2027 Mirror Notes Indenture.

Certain covenants will cease to apply to the 2027 Mirror Notes if, and for so long as, the 2027 Mirror Notes have investment grade ratings from any two of Moody’s Investors Service, Inc., Fitch Ratings, Inc.

and S&P Global Ratings, and so long as no default or event of default under the 2027 Mirror Notes Indenture has occurred and is continuing.

Upon suspension of the covenants, the Guarantees will be released until such time as the covenants are no longer suspended.

The principal amount of the 2027 Mirror Notes would become immediately due and payable upon the occurrence of certain bankruptcy or insolvency events and may be declared immediately due and payable by the 2027 Notes Trustee or the holders of at least 25% of the aggregate principal amount of the then-outstanding 2027 Mirror Notes upon the occurrence of certain events of default under the 2027 Mirror Notes Indenture.

Events of default include the following with respect to the Issuers’ and Group’s significant subsidiaries:

(i) failure to pay principal, premium or interest at required times;

(ii) failure to comply with any other agreements in the 2027 Mirror Notes Indenture;

(iii) default on certain material indebtedness that is caused by a failure to make a payment within any applicable grace period when due at maturity or results in the acceleration of such indebtedness prior to its express maturity;

(iv) failure to pay certain material judgments;

(v) a Guarantee being held unenforceable or invalid or ceasing for any reason to be in full force and effect or a Guarantor denying or disaffirming its obligations under its Guarantee;

and (vi) certain events of bankruptcy or insolvency.

Issuance of $206.0 Million Principal Amount of IPv4 Notes

On May 2, 2024, the IPv4 Issuer, our special-purpose, bankruptcy remote, indirect wholly owned subsidiary, issued $206.0 million aggregate principal amount of IPv4 Notes, with an anticipated term ending in May 2029 (such anticipated repayment date, the “ARD”), in an offering exempt from registration under the Securities Act.

The net proceeds from the offering, after debt offering costs, were $198.4 million and are expected to be used for general corporate purposes.

The IPv4 Notes were issued pursuant to an indenture, dated as of May 2, 2024 (the “IPv4 Base Indenture”), as supplemented by the Series 2024-1 Supplement thereto, dated as of May 2, 2024 (the “Series 2024-1 Supplement”), in each case entered into by and between the IPv4 Issuer and Wilmington Trust, National Association, as the trustee for the IPv4 Notes (the “IPv4 Trustee”).

The IPv4 Base Indenture allows the IPv4 Issuer to issue additional series of notes subject to certain conditions set forth therein, and the IPv4 Base Indenture, together with the Series 2024-1 Supplement, and any other series supplements to the IPv4 Base Indenture, is referred to herein as the “IPv4 Indenture.”

The IPv4 Notes were issued as part of a securitization transaction, pursuant to which certain Internet Protocol version 4 (“IPv4”) addresses, customer IPv4 address leases, customer accounts receivables and other IPv4 address assets (collectively, “IPv4 Address Assets”) were contributed or sold to the IPv4 Issuer and are included as collateral for the IPv4 Notes.

While the IPv4 Notes are outstanding, scheduled payments of interest are required to be made on a monthly basis.

From and after the ARD, principal payments will also be required to be made on the IPv4 Notes on a monthly basis.

No principal payments will be due on the IPv4 Notes prior to the ARD, unless certain rapid amortization or acceleration triggers are activated.

Cogent Communications LLC (in such capacity, the “Manager”) performs certain monthly services related to the IPv4 Address Assets and IPv4 Notes including billing customers, collecting amounts paid by customers, forwarding payments to the IPv4 Trustee related to the IPv4 Address Assets and other administrative services.

Amounts paid by the Manager to the IPv4 Trustee are reconciled on a monthly basis and the IPv4 Trustee pays the monthly interest on the IPv4 Notes and other expenses from the accumulated customer payments on the IPv4 Address Assets.

Amounts held by the IPv4 Trustee before the monthly reconciliation is completed are considered restricted cash.

After the IPv4 Trustee pays the monthly interest and other IPv4 Address Asset related costs, including monthly fees paid to the Manager for its services, the residual cash is paid to us and is unrestricted.

Page 44 of 96

The legal final maturity date of the IPv4 Notes is in May of 2054.

If the IPv4 Issuer has not repaid or refinanced the IPv4 Notes prior to the monthly payment date in May of 2029, additional interest will accrue thereon in an amount equal to the greater of (i) 5.0% per annum and (ii) the excess amount, if any, by which the sum of the following exceeds the interest rate for such IPv4 Note:

(A) the yield to maturity (adjusted to a “mortgage-equivalent basis” pursuant to the standards and practices of the Securities Industry and Financial Markets Association) on the ARD for such IPv4 Note of the United States Treasury Security having a remaining term closest to 10 years;

plus (B) 5.0%;

plus (C) the post-ARD note spread of 3.400% applicable to such Note.

The IPv4 Notes are obligations only of the IPv4 Issuer pursuant to the IPv4 Indenture, and are secured by a security interest in substantially all of the IPv4 Address Assets pursuant to the IPv4 Indenture.

The IPv4 Notes are guaranteed by Cogent IPv4 Holdco LLC, a special-purpose entity and our indirect wholly owned subsidiary, as the guarantor (the “IPv4 Guarantor”), pursuant to a guaranty dated as of May 2, 2024 (the “Guaranty”), by the IPv4 Guarantor in favor of the IPv4 Trustee, pursuant to which the IPv4 Guarantor has granted a security interest in the equity interests of the IPv4 Issuer as collateral security for its obligations under the Guaranty.

Except as described below, neither we nor any of our subsidiaries, other than the IPv4 Issuer and the IPv4 Guarantor, will guarantee or in any way be liable for the obligations of the IPv4 Issuer under the IPv4 Indenture or the IPv4 Notes.

The IPv4 Notes are subject to a series of covenants and restrictions customary for transactions of this type.

These covenants and restrictions include (i) that the IPv4 Issuer maintains a liquidity reserve account to be used to make required payments in respect of the IPv4 Notes such amount considered restricted cash, (ii) provisions relating to optional and mandatory prepayments, including specified make - whole payments in the case of certain optional prepayments of the IPv4 Notes prior to the monthly payment date in May of 2028, (iii) certain indemnification payments in the event, among other things, that the transfers of the assets pledged as collateral for the IPv4 Notes are in stated ways defective or ineffective and (iv) covenants relating to recordkeeping, access to information and similar matters.

As provided in the IPv4 Base Indenture, the IPv4 Notes are also subject to rapid amortization in the event of a failure to maintain a stated debt service coverage ratio as defined in the IPv4 Indenture.

A rapid amortization may be cured if the debt service coverage ratio exceeds a certain threshold for a certain period of time, upon which cure, regular amortization, if any, will resume.

In addition, if certain utilization thresholds are not met (i.e., the proportion of IP addresses that are leased to the total number of IP addresses owned by the IPv4 Issuer falls below certain thresholds), the IPv4 Issuer will be required to apply collections to the repayment of the IPv4 Notes, and in certain circumstances, the noteholders will have the ability to direct a sale of the IP Address Assets, in whole or in part, pursuant to the terms set forth in the IPv4 Indenture.

The IPv4 Notes are also subject to certain customary events of default, including events relating to non - payment of required interest, principal or other amounts due on or with respect to the IPv4 Notes, failure to comply with covenants within certain time frames, certain bankruptcy events, breaches of specified representations and warranties, failure of security interests to be effective and certain judgments.

Limitations Under the Indentures

The indentures governing the 2026 Notes, the 2027 Notes and the 2027 Mirror Notes (the “Indentures”), among other things, limit the ability of Group and its restricted subsidiaries to incur indebtedness;

to pay dividends or make other distributions;

to make certain investments and other restricted payments;

to create liens;

to consolidate, merge, sell or otherwise dispose of all or substantially all of its assets;

to incur restrictions on the ability of a subsidiary to pay dividends or make other payments;

and to enter into certain transactions with its affiliates.

There are certain exceptions to the limitations on the ability to incur indebtedness under the Indentures, including IRU agreements incurred in the normal course of business and any additional indebtedness if Group’s consolidated leverage ratio, as defined in the Indentures, is less than 6.0 to 1.0 or Group’s fixed charge coverage ratio, as defined in the Indentures, is 2.0 to 1.0 or greater.

Future Capital Requirements

Any future acquisitions or other significant unplanned costs or cash requirements in excess of amounts we currently hold may require that we raise additional funds through the issuance of debt or equity.

In addition, our 2026 Notes will mature in May 2026.

At that time we will need to repay our 2026 Notes which may require us to issue additional indebtedness.

We cannot assure you that such financing will be available on terms acceptable to us or our stockholders, or at all.

The accounting policies we believe to be most critical to understanding our financial results and condition or that require complex, significant and subjective management judgments are discussed below.

Acquisition accounting

In connection with our acquisition of the Sprint Business we made the following significant changes to our critical accounting policies and significant estimates.

For the fair values of the assets acquired and liabilities assumed, we used the cost, income and market approaches, including market participant assumptions.

Page 48 of 96

In connection with the Transaction, the identifiable assets acquired and liabilities assumed were recorded at their fair values as of the acquisition date.

Assigning fair market values to the assets acquired and liabilities assumed at the date of an acquisition requires the use of significant judgment regarding estimates and assumptions.

We acquired property and equipment comprised of the legacy Sprint network and consists of optical fiber, related equipment, and owned real estate.

Management valued these assets using factors that represent an orderly liquidation value, to approximate the highest and best use of assets acquired in a distressed business.

The valuation of the optical fiber requires the estimation of the total replacement cost per mile of fiber and a factor to reflect the orderly liquidation value.

There is not active market data for these assumptions and these assumptions are inherently subjective.

Market participants could have differing views on these assumptions, which could result in a materially different fair value of the optical fiber.

On the Closing Date, we entered into the IP Transit Services Agreement.

We evaluated what elements were part of the business combination and the consideration exchanged to complete the Transaction.

We concluded that the payments to be made represent consideration received from T-Mobile to complete the acquisition of a distressed business.

We concluded that T-Mobile did not represent a customer, the stated contract price did not represent consideration for services to be delivered, and the transaction did not satisfy the definition of revenue.

We also considered whether the IP Transit Services Agreement would be considered separable from the business combination.

We concluded that the cash consideration was not separately identifiable from the business combination and was therefore not meant to be in exchange for a distinct good or service.

As a result, the IP Transit Services Agreement was recorded in connection with the Transaction at its discounted present value resulting in a discount.

The interest rate used in determining the present value was derived considering rates on similar issued debt instruments with comparable durations, among other market factors.

The determination of the discount rate and the conclusions reached related to the IP Transit Services Agreement required significant judgment.

The Purchase Agreement includes an estimated payment from Seller to Buyer related to short-term lease obligations.

This amount was recorded at its present value resulting in a discount.

The interest rate used in determining the present value was derived considering rates on similar issued debt instruments with comparable durations, among other market factors.

The determination of the discount rate requires some judgment.

Intangible Asset

In connection with the Transaction, we recorded an intangible asset totaling $458.0 million for acquired IPv4 addresses.

This asset was recorded once management determined both the quantity of IPv4 addresses for which title was transferred and the valuation approach.

Because of the novel nature of this asset and that the Transaction has resulted in a material bargain purchase gain, management recorded the asset after appropriate consideration of the valuation approach, in the context of a distressed business.

The fair value measurement of the IPv4 addresses was based on recent auction prices and a factor to incorporate the uncertainty for how the market for IPv4 addresses will function in the future.

We believe that these IPv4 addresses have an indefinite useful life and are not being amortized.

We evaluate the IPv4 intangible asset for impairment on the first day of the fourth quarter, or more frequently if events or changes in circumstances indicate that the carrying amount may not be recoverable.

In performing our impairment assessment, we first evaluated qualitative factors to determine whether it is more likely than not that the fair value of the indefinite-lived intangible asset is less than its carrying amount.

The fair value measurement of the IPv4 address asset was recorded in purchase accounting in the context of the acquisition of a distressed business with a material bargain purchase gain, based on recent auction prices and a factor to incorporate the uncertainty for how the market for IPv4 addresses will function in the future.

We believe that the IPv4 address asset has an indefinite useful life and is not being amortized.

We evaluate the IPv4 address intangible asset for impairment on the first day of the fourth quarter, or more frequently if events or changes in circumstances indicate that the carrying amount may not be recoverable.

The factors we evaluated include market data for sales and leases of IPv4 addresses and cash flows associated with the asset.

Upon consideration of these factors, we determined that it was not more-likely-than-not that the asset was impaired, and that a quantitative impairment assessment was not required.
